[SOLVED] Is there any use of unionall in laravel eloquent?

Is there any use of unionall in laravel eloquent?

I am pulling two different data from the same table in the database.I'm merging this data with union but not all results are shown. So I want to use unionAll. Can I use it with Eloquent?

My code:

$model = OrderDetail::with('product')->whereBetween('created_at', [Carbon::createFromDate($request['year_first'])->startOfYear(), Carbon::createFromDate($request['year_first'])->endOfYear()])->get()->groupBy(['service_id'])
                ->union(OrderDetail::with('product')->whereBetween('created_at', [Carbon::createFromDate($request['year_last'])->startOfYear(), Carbon::createFromDate($request['year_last'])->endOfYear()])->get()->groupBy(['service_id']));

When I try with unionAll() I get the following error:

Method Illuminate\Database\Eloquent\Collection::unionAll does not exist.

Does unionAll() have different uses?

Solution

Your query uses union from the collection not the union of the query builder. This is because you have a get() before the union. To get a rather similar (but probably not identical) result to what you need you can do:

$model = OrderDetail::with('product')->whereBetween('created_at', [Carbon::createFromDate($request['year_first'])->startOfYear(), Carbon::createFromDate($request['year_first'])->endOfYear()])
                ->unionAll(OrderDetail::with('product')->whereBetween('created_at', [Carbon::createFromDate($request['year_last'])->startOfYear(), Carbon::createFromDate($request['year_last'])->endOfYear()]))
     ->get()->groupBy(['service_id']);

This makes union and unionAll usable in that part of the query. Sidenote you might have issues with the eager loading, I've not checked if it can happen in a union query.
